Product Description

This PR2002 vacuum regulator is a low profile vacuum regulator designed for use with Walker CCE Airsep systems. In addition to regulating vacuum in the AIRSEP system, it incorporates a pressure relief valve to further protect your engine from high crankcase pressure should your internal coalescer (oil mist) filters plug. Should oil mist vent from the relief port, you must replace the internal coalescer set. NOTE: Coalescer elements cannot be cleaned and must be replaced. Included in CCE AIRSEP systems from 2002 to present, this regulator also offers improved response time to better match engine changes at various RPM when the main air filter is in a restrictive condition. The PR2002 regulator is maintenance free, and is not designed to be disassembled.. Compatible with CCE AIRSEP systems only (using V-band clamps to attach the air filter to the AIRSEP body), traditional AIRSEPS use the VR1000 or PR2000 regulators. NOTE: Do not select if you have an older traditional AIRSEP, a different regulator is required (VR1000 or PR2000). Convenience and premium quality come together with this Genuine Walker replacement part. Walker Part# PR2002

Marine Parts and Expert Support Since 1988

When purchasing parts for a marine engine, generator, transmission or filtration system, choosing the correct product is essential. Hall Engine Company provides customers with more than access to quality marine products—we also offer the experience and personal service needed to help make the right selection.

Family-Owned and Operated Since 1988

Hall Engine Company has served vessel owners, captains, engineers, boatyards and marine professionals since 1988. As a family-owned and operated company, we believe customer relationships matter. We take pride in providing the personal attention and practical assistance customers may not receive from a large, automated online retailer.

Our business was built by serving customers directly, understanding their vessels and helping resolve real marine engine and equipment concerns. That customer-first approach remains central to how we operate today. Whether you are ordering routine maintenance supplies or searching for a specialized replacement component, our team is committed to making the process clear and dependable.

Assistance Selecting the Correct Product

Marine parts should not be selected by appearance alone. Compatibility may depend on the manufacturer, model, serial number, horsepower, installation design and existing part number. Even products that look similar may have different dimensions, connections or application requirements.

If you are uncertain whether this product is appropriate for your vessel, contact Hall Engine Company before ordering. Our experienced team can review the information you provide and help determine whether the product is suitable for your application.

Information That Helps Us Assist You

When requesting assistance, please provide as much information as possible. Helpful details may include:

  • Vessel make, model and year
  • Engine or generator manufacturer
  • Equipment model and serial number
  • Existing part number
  • Photographs of the current component
  • Measurements or installation details
  • A description of the maintenance or repair

These details help our team understand your application and offer more accurate guidance. If additional information is needed, we will explain what to locate and where it may be found on your equipment.

Customer Service Is Our Priority

We understand that customers may be ordering for scheduled maintenance, an active repair or a vessel that needs to return to service quickly. Our team works to answer questions clearly, confirm available product information and help customers avoid preventable ordering mistakes. If an application requires additional verification, we would rather review it carefully than recommend a product without sufficient information.

Shipping Across the USA and Internationally

Hall Engine Company offers shipping throughout the United States and to international destinations. Whether your vessel is located in South Florida, elsewhere in the country or outside the United States, our team can help coordinate shipment of available products.

Shipping costs and delivery times depend on the product, destination, carrier and service level. International shipments may be subject to customs requirements, import duties, taxes or brokerage charges. For urgent, oversized or international orders, contact us before completing your purchase so we can review the available options.
